Variance is calculated by subtracting the average return from each individual return, squaring that figure, summing the squares across all observations, and dividing the sum by the number of observations. The square root of the variance, called the standard deviation or the volatility, can be used to estimate risk.

Value at Risk (VaR) is a powerful measure that captures key aspects of risk: Amount: It quantifies potential losses, providing a clear understanding of the financial impact in case of adverse events. Probability: It considers the chance of experiencing those losses, allowing users to assess the likelihood of risk occurrence.The value at risk is $1.7 million. In other words, the market risk of this portfolio can be communicated effectively to a non-technical audience with a statement such as: Under normal market conditions, the most the portfolio can lose over a month is $1.7 million. It is the probability that a portfolio will experience a mark-to-market loss that exceeds that of a specific predetermined threshold value. Essentially this means that value at risk is measured in three variables: The timeframe. The most common parameters for VaR are 1%, 5%, and 10% probabilities and time periods of one day, two weeks, or a month. 11.3 Calculating Value-at-Risk With Historical Simulation; 11.4 Origins of Historical Simulation; 11.5 Flawed Arguments for Historical Simulation; 11.6 Shortcomings of Historical Simulation; 11.7 Further Reading; 12 Implementing Value-at-Risk. 12.1 Motivation; 12.2 Preliminaries; 12.3 Purpose; 12.4 Functional Requirements; 12.5 Build vs. Buy ...It calculates potential losses over a period, with a specific level of confidence.
